AMD Ryzen Discussion Thread.

[Tatty_Two]

in that link he says benchmarks were completed at default values. no overclock. just after he says what he reached overclocking. I think that is very misleading. of course the ryzen chip did badly. remember we found that by using faster memory and increased the infinity fabric speed and gaming performance beat all of intels chips in 80percent of games...i'll come back and post a link when I come across the source again. I remember the intel chips also benefitting up to 3200mhz and then it levelled out. the amd system carried on increasing in performance. I'm not bothered if my maximum frames are lowered. as long as the minimum frames are high I'm fine with it. although I am using a titan.
quote
The new power plan gives almost identical performance to the High Performance plan, but when the machine is idle, it offers some, if not all, of the power saving that the Balanced setting provides.

AMD should also be addressing some problems on its side. Ryzen shows a significant dependence on the speed of its memory. Faster memory obviously means that there is more bandwidth, but there's a less obvious advantage on Zen chips: internally, the chip is organised as two blocks of four cores, and the communication between these blocks of four cores runs at the memory clock speed. Make the memory clock faster by going from, say, 2400MHz RAM (on a 1200MHz clock) to 3200MHz RAM (on a 1600MHz clock) and not only does the memory bandwidth go up by fifty percent, but so too does the bandwidth between the two blocks of cores.

That appears to be quite the opposite of W1z's dedicated Ryzen memory speed review where it showed minimal gains in gaming...........................

So, I got some Corsair LPX 3200 memory and I still have the same problem. Only 8GB accessible in Windows 10, the rest is "hardware reserved" and I can't change any memory settings, as the board ends up in a failover loop until the watchdog kicks in and tells me to press F1 as the "overclocking" failed.

Do I have a borked board or processor? As it's the only thing I can think of at this point. Asus support has been useless and are just telling me that they don't have the RAM to test with.

This may be a really dumb question but did you install the 64-bit version of Windows? And not the 32-bit version. Why I ask is that I have seen something similar to what you are seeing @TheLostSwede when people install the wrong version.

it does and that's to do with Elmore writing a new bios every week since release.
I'm sure w1z will return to ryzen memory improvements when the next big bios is released with new memory dividers.

got my system up and running and I have to say that the working machine is pretty impressive. for everyone else, careful when performing a fresh install. make sure you allow windows to update and make sure to get your chipset driver from amd directly.
everything should install properly and you wont run into any trouble like I did with the gpu...

I haven't used a 32-bit OS since Windows 7 launched. This isn't my first build, but thanks for your concern.
This is what happens, and I have now plonked the other 16GB in the board, which resulted in 16.1GB of hardware reserved memory.

I have never come across this issue before and all the "solutions" I've found online don't work. I'm really at a loss here, in addition to the fact that I can't change a single memory setting in the UEFI and this is also regardless of UEFI version.

 

[trparky]

Since most Windows 10 installation media comes with both 32 and 64-bit installation media I was thinking perhaps you chose the wrong install type. I made that mistake one day. I accidentally chose the wrong one. I double tapped the down arrow on the keyboard by accident.

Sure, mistakes happen, but as you can see, that's not the issue. Even so, a 32-bit OS would only give me 4GB, not 8GB of RAM.

However, as you can see, the UEFI only shows 8GB, not 16GB, so there's something seriously weird going on here.

Try going to MSConfig>boot>advanced check that the max memory isn NOT checked. This should be blank if it's checked then uncheck it and reboot.

Tried that and the other five or six different "solutions" for this problem, at no avail.

Now that I see it's not showing in BIOS you likely have a bad channel on the board or possibly a bent pin(s) on the CPU

Doesn't matter which slots I use for the RAM. All the RAM is visible to Windows, regardless of if I insert 2x 8GB or 4x 8GB, but the UEFI does not see the memory properly. However, it does see all four DIMMs as present, it just doesn't want to let me access more than half of whatever I put in the board. I've now tested with Crucial Ballistix Tactical which is my old RAM and some brand new Corsair LPX modules, same problem.

 

[Johan45]

Is there a newer BIOS than 601?

 

[Caring1]

Try a clean install, I know it's not what you want to hear, but it might clear the bugs out.

 

[TheLostSwede]

Ok, this makes no sense at all. Just to check, I took out he CPU, no bent pins, put it back, did a hard CMOS reset and all of a sudden it works. This is admittedly with the new Corsair LPX RAM and I can now run it at 2933MHz.

No idea what's going on, but I'm happy as can be right now

 

[Johan45]

At a guess poor contact in the socket, the remount probably lined things up again.
I have seen this almost everytime I cold bench FX CPUs. I have to "re-adjust" the CPU after everything is frozen
Glad it's working for you though

 

[trparky]

Maybe the BIOS reset fixed it, maybe it lost its mind.

 

[TheLostSwede]

Well, I really couldn't say, but hey, at least it all looks good now, or as good as we can expect until better UEFI's are released by Asus. https://valid.x86.fr/76famx

I was going to respond to your prior post that it sounds like a RAM incompat problem, which is why it's always best to stay within their QVL. If ASUS says they don't have the RAM to test with, it probably isn't on the QVL.

I know technically both are Corsair LPX, but if they made some update to it, it should have a different model number, which is why you always check QVL model numbers, not model names.

Anyways, I have a sneaking hunch this is more to do with AMD's not being communicative enough with MB and RAM manufacturer's about memory for AM4, even though it's about capacity vs frequency.

btw if you buy 2 1080's due to the drivers being immature you will get less performance than you do with one card in virtually every game except a couple of benchmarks which do show an improvement.

SLI and Crossfire are to be avoided always. It's not the drivers. It simply isn't a perfect technology and it will never be.

new bios out today..1201.. id try that... hopefully it helps...

still AGESA 1.0.0.4a, was expecting 1.0.0.5, but i'd probably give it a try anyway......

NEW BIOS 9945 with dividers for 4000mhz available!!!!!!!!!!
